STM32 MCUs Products

Hi, I am seeking product recommendations from you for developing our project using an NXP board. We require a simple and cost-efficient board suitable for a medical patient monitor. Key considerations include interfacing with a 12-lead ECG module (SPI port), a temperature sensor, NIBP, SpO2, and a TFT display interface port. Additionally, the system should be capable of printing the ECG wave on a thermal printer. The LCD panel should be easy to interface with. We prefer a board with an M4 processor or one capable of utilizing memory for storage. The price range we are considering is between $0-100. I am attaching a rough block diagram to give you a better idea of our requirements Updating Mediaalso,i got few suggestion in nxp product,so plz compare to them, and give equivalent or better than it.i give linksThis is LPC5462x link:

Hi,I am configuring TIM1 to generate interrupt via MX and I can see that the ISR for TIM1 break is added to the code.But the interrupt never triggers. I know that break from comparator does happen, but no interrupt!Does anyone know what could be wrong?

Hello, I'm trying to configure my NUCLEO-U575ZI-Q to read multiple channels of ADC at once. I will describe the settings in the following and then raise my questions:1- I use IN1 and IN2 on ADC4 which corresponds to PC0 and PC1 on the EVB2- I set scan conversion mode to Forward (which I guess it means read first PC0 and then PC1 right?)3- Continuous conversion mode is disabled4- DMA continuous requests is Enabled (the strange part is that this option doesn't exist for ADC1. Will appreciate if someone can explain the reason and the meaning of it)5- End of Conversion selection is set to End of Sequence of conversion (not single conversion) which should mean the EoC is True only after the two channels are converted (right?)6- SamplingTime common 1&2 are set to 7.5 (I'm not sure why there are two)7- Trigger Frequency is set to Low8- I'd like to use Regular Conversion Launched by SW at the beginning and later use a

Hello every body.MCU：STM32F103RBT6  LQFP-64 PackagePWM Capture in on PA6(TIM3-CH1)The PWM Capture signal source is Frequence is 50KHZ to 1.0MHZ, Duty cycle and Frequence always change by loading switch.PWM Out Function on foue output are：PA8(TIM1-CH1) PA10(TIM1-CH3) & PB8(TIM4-CH3) PB10(TIM2-CH3)My Question as below.Question 1：I can capture in PA6(TIM3-CH1) Duty cycle and Frequence is okay(TIM3-CH1 detect rise edge,TIM3-CH2 detect falling edge，and I used the Interrupt capture in the signal, and used the PA6(TIM3-CH1) master trigger(TRGI) to another PWM out as PA8(TIM1-CH1) PA10(TIM1-CH3) & PB8(TIM4-CH3) PB10(TIM2-CH3), The foue output trigger by ITR2(TIM3)-TRGI used the TI1FI1 or TI1F_ED.How can i do the four output PA8(TIM1-CH1) PA10(TIM1-CH

I have been trying to read the ultrasonic sensor data from STM32F072-Nucleo and transmit the received data to STM32F746G using URAT configuration but the problem is unable to receive the data . As per the data sheet pins(0,1)are dedicated to UART but no data we are getting on the side  of STM32F746G but observed no code errors and warnings .

Hi all,I'm experimenting on an STM32F723disco board, trying out some audio DSP. I seem to be getting abysmal processing speed.So as a first sanity check I did a simple nop timing test:Turn on a GPIO pin, do 50 nops, turn the GPIO pin off. (By 50 nops, I mean 50 lines saying asm("nop") )Turn the GPIO pin on again, do 100 nops, turn the GPIO pin off.This gives me two pairs of pulses, the difference in length of which should correspond to the 50 extra nops the second time around. Result: it seems a nop takes around 9.6ns, which is two clock cycles.Curiously, ART wasn't enabled, but setting the ARTEN bit had no impact anyway.I must be doing something terribly wrong.Cheers,B.

We want to do parallel communication. How can we do parallel communication with the following microcontroller?Is it possible to perform parallel communication by using I2C function?[IDE]STM32CubeIDE 1.14.0[MCU] STM32F412VGT6

Hi,I am working with STM32G4.I am communicating with STM32G4 with other controller through  UART communication.I can able to receive the data from other MCU to STM32G4 all the time but sometimes I can't able to transmit data from stm32g4 to other MCU.I used UART PollForConversion method  for development.I receive the data from other MCU to STM32g4 for every 1sec.Below is the STM32G4 side code: uint8_t ocpp_txdata[64]; uint8_t ocpp_rxdata[8]; while(){ HAL_UART_Receive(&huart5,ocpp_rxdata,7, 1000); uint16_t calculatedCRC; uint16_t receivedCRC; if(ocpp_rxdata[0]==0x22) { calculatedCRC = HAL_CRC_Calculate(&hcrc,(uint32_t *)&ocpp_rxdata, 4); receivedCRC=ocpp_rxdata[4]<<8 | ocpp_rxdata[5]; if(calculatedCRC==receivedCRC){ switch(ocpp_rxdata[2]) { case 0x01: //trasmit data ocpp_txdata[0] to ocpp_txdata[18] //ocpp_txdata[16],ocpp_txdata[17] is crc HAL_UA

Hello,I'm trying to do SPI communication with an ADE1201 chip through an STM32H753VIT6 chip.The maximum allowed frequency of the ADE1201 is 10MHZ, so I set the SPI to communicate with the MCU at 6.25MHZ.(The clock for SPI communication is 25MHZ, and I set the PRESCALER value to 4).However, a strange phenomenon was observed. I observed through the scope that the SPI CS signal should be 0 continuously, but it turns to 1 in the middle.(See attached photo).However, if I set the PRESCALER value to 8, the CS signal is continuously output as 0. What could be the cause? And how can I solve this?

 Thanks for the response. which filter algorithm is best to find heading in stm32 mcu form 9 axis imu sensor?.Any documents or libraries available for same ?

Hi all,I'm trying to use Timer16 to create a 50Hz timer to save files in the SD card. I managed to make the timer work blinking a LED, but when I put the code to save it only saves one line. Here's the logic:First I create a file  and initiate the timer in the USER CODE BEGIN 2 (I want to state that if I start the timer after the SD has been created, it doesn't work (don't know why)).//TimerHAL_TIM_Base_Start_IT(&htim16);//Mount SDfresult = f_mount(&fs, "", 0);f_getfree("", &fre_clust, &pfs);total = (uint32_t)((pfs->n_fatent - 2) * pfs->csize * 0.5);bufclear();free_space = (uint32_t)(fre_clust * pfs->csize * 0.5);//Open file to read / create it if it doesn't exist//fresult = f_open(&fil, file_name, FA_OPEN_ALWAYS | FA_WRITE);fresult = f_open(&fil, "testeTimer2.csv", FA_OPEN_ALWAYS | FA_WRITE);f_gets(buffer, f_size(&fil), &fil);fresult = f_lseek(

My project to have USB VCP UART working on NUCLEO-U575 as well as NUCLEO-U5A5 boards (via a compile macro).Use the USB-C USR USB connection as a USB based UART (COM port on host): any baud rate as supported by USB speed (FS vs. HS). There is a second UART via the ST-LINK (baud rate: 1843200): so, you have two USB based UARTs - in parallel.The project is here:https://github.com/tjaekel/NUCLEO-U5A5JZ-Q_QSPI It provides already a command line (shell), to interpret the entered line as a command to execute. Extend the list of commands - if you like. Enter "help" to see list of implemented commands.

I'm trying to read i2s data on F401 from a dummy master device with slow clock rate.The problem is that it only reads the first channel correctly, rest is gibberish, based on logic analyzer the rest of data is there. so I generate this simple test data with bitbang going into F401, content should be: 0001 0203, 0405 0607, 0809 0A0B  (only last is displayed)zoomed out:

Hello, after a long search for an answer to my problem, I still couldn't find a solution. Perhaps one of you can help me.I use the MCU STM32G071RBT6 (with 128KB FLASH) and to upload .bin file via UART I use the old program STM32Flashloader.exe.  As .STmap file I use STM32F0_7x_128K.STmap.My bootloader function looks like this:void ServiceBootJump(void){     void (*SysMemBootJump)(void);                                                                                         

I've been banging my head against this one for a while.  I have two pins I'm trying to generate a peripheral-timed pulse on, which sounds like a perfect fit for One Pulse Mode."Trigger 1" is TIM8 CH1; that is, PB6."Trigger 2" is TIM1 CH3; that is, PA10.The two timers are configured identically, produce different results, neither of which are correct.I have simplified my project to run a simple loop, theoretically continually triggering single pulses every two seconds.  TIM8 CH1 generates a runt followed by a permanently-high state; TIM1 CH3 never goes high.I found this post which sounded just like the problem I was having, but that person's solutions did not work for me.  That post does make the important observation (that I als

 Is it OK to use DWT CYCCNT to count individual instruction cycles when stepping instructions (si) with gdb ? I wonder how many cycles a branch takes when it is taken.

Hi, i'm moving from IAR to STM32CubeIDE all my projects based on STM32 microcontrollers. On IAR i modified the entry point of the project from 0x8000000 to 0x8008000. How may do same modify on CubeIDE? Thanks.Massimo Liggio 

Hi,I have a board that I designed using the STM32F750Z8. It transfers data from a Himax hm01b0 image sensor via the DCMI port to USB using DMA.This is a stripped down version of my FreeRTOS thread that initializes and reads the image sensor. I've removed parts that I feel are irrelevant.   void camera_task(void const* args) { camera_frame_ready_semaphore = xSemaphoreCreateBinaryStatic(&camera_frame_ready_semaphore_buffer); // ... // initialize image sensor power supply and clock. // image sensor does not start sending frames yet. pclk, vsync, and hsync are inactive. // ... // enable DMA clock __HAL_RCC_DMA2_CLK_ENABLE(); __HAL_RCC_DCMI_CLK_ENABLE(); osDelay(1); // setup DCMI #if 0 DCMI->CWSIZER = (239 << 16) | (((320 * 2) - 1) << 0); // image is 640 x 240 (this is correct.) DCMI->CWSTRTR = ( 2 << 16) | ( 4 << 0); // 2x4 pixel border ar

I am using STM32F429VIT6. Configured SystemCoreClock 168MHz and APB2 clock is 84MHz. I accidentally configured ADC peripheral with "ADC_CommonInitStructure.ADC_Prescaler = ADC_Prescaler_Div2;" but datasheet says max ADC frequency is 36MHz. I am wondering about my ADC peripheral clock:- Is it running at 42MHz with overclocking? or- Is it running with max freq. so it is 36MHz? or- Is it running with typical freq. so it is 30MHz? or- Is it ignore ADC_Prescaler_Div2 and process it with ADC_Prescaler_Div4 so it is 21MHz?

Good afternoon, I am developing an hardware with microcontroller in Object. I'm using the LQFP208 package because in my opinion it's easier to solder/remove in my lab. For my application I need the support for: ETHERNET FMC for SDRAM QUADSPI SDMMC1 USB OTG FS LTDC UART, I2C and SPI when I try to create the IOC file I have some problems with the FMC setting for the SDRAM. All the peripherals end with the green check instead I have a warning on the FMC and so I don't understand whether or not I can use this processor with these requirements. Anyone could help me? Thanks in advance Alfredo  

I am testing the initialization module.The issue is that while debugging, when I set a break point in the if statement or use the printf statement above the while in the sample below, it hangs.It seems to be an event related issue, is there any way to handle this?In particular, if I use a lot of printf statements, I get hung.device : STM32F103xE debugger(driver) : j-link IICcnt = 0; while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_BYTE_RECEIVED)) { if( IICcnt > IICMAXDELAY ) // breakpoint to here. { /* Send STOP condition */ I2C_GenerateSTOP(I2C1, ENABLE); /* Clear EV6 by setting again the PE bit */ I2C_Cmd(I2C1, DISABLE); ret = ERROR_I2C_READDATA_RDDATA; } }

Hello,i am working on a diy project which inculdes the interfacing of MPU6050 with STM32F103C8.I am using KEIL IDE to code.The libary am using is from here:https://github.com/leech001/MPU6050This library has kalman filter too, which is great for my purpose.Unfortunately calculating the yaw is not correct (i don't mean in the library)Using the library and it's kalman filter i get the roll and pitch correctly but not the yaw.Is it possible to get the yaw too using MPU6050?Any help is appreciated

I have a project ported from STMU575-EV board to NUCLEO-U575 as well as now also NUCLEO-U5A5 (providing an USB device).It is an USB ECM application (demo) - but it shows you the differences between all the different boards used, in terms of USB initialization and use.It should help also to get an USB VCP (CDC, ACM) project working with both boards.If you want to see how the USB differs on a U5A5 (which has an USB OTH HS PHY integrated) vs. an U575 (with has just an USB OTH FS), and how to use U5A5 HS PHY also for FS speed...:you can have a look at my project:https://github.com/tjaekel/STM32U5xx_USB_ECM The
