STM8 MCUs

as per datasheet of stm8s001j3 it has been mentioned that impact of pin mode while using other pins, ex. PD1 impacts PD6,PD5... so to disable the swim pin using Out Mode Low Level, would also impact in case want to set late for PD5 as IN Mode FL NO IT pin. which means that i need to always set PD1 as Input Floating Pin to use it for PD5 analog channel 5?

Hi :) I am doing a project where I need a (relatively) accurate crystal. I have never used special precision crystals but my guess is a normal crystal would do. I would like though to have the best accuracy possible by laying out the PCB and choosing the capacitors accordingly.The project uses an STM8L151G6U6, and the datasheet shows an input capacitance of 2.6pF.My crystal has a load capacitance of 9pF.My crystal traces are 10mil thick and about 300mil each - see the picture below. If I assume a stray+pin capacitance of 5pF total, that means I should choose (2*9) - 5 = 13pF, so I would choose a 12pF cap.

Hi again =) ​I have a small project with an STM8 and I was thinking driving my 3-digit 7 segment display directly with the MCU in order to reduce the manufacturing price (I know some of these chips cost only a few cents but if I *can* do it directly from the MCU then is there a reason not to?).This is my setup:​​The display is common anode, and the transistors are PNP. Each blue label is directly connected to a pin on the MCU.The MCU is a STM8L151G6U6.The display datasheet says about 1.8V to 2.2V forward voltage and max 20mA current.The datasheet of my STM8 says max 25mA per pin - so far so good. But it also says only 80mA on the VCC &a

The example from STM8L15x-16x-05x-AL31-L_StdPeriph_Lib doesn't explain the way a regular buffer (i.e. 20 - 30 bytes of data) exchange between two MCUs in master and slave mode. Can anyone explain the steps of configuration on both sides?Now I have STM32 MCU acting as a master (for testing only), and sending a few bytes in burst mode five times per second. A slave, STM8L151K4, supposed to receive the command and return the status data (ADC and GPIO).My SPI and DMA configurations for slave are (please disregard commented):void SPI_Config(void){ GPIO_DeInit(SPI_PORT); GPIO_Init(SPI_PORT, CLCK_PIN | MOSI_PIN | nSS_PIN, GPIO_Mode_In_PU_No_IT); GPIO_Init(SPI_PORT, MISO_PIN, GPIO_Mode_Out_PP_High_Fast); //GPIO_ExternalPullUpConfig(SPI_PORT, CLCK_PIN | MOSI_PIN | nSS_PIN, ENABLE); SPI_DeInit(SPI1); SPI_Init(SPI1, SPI_FirstBit_MSB, SPI_BaudRatePrescaler_2, SPI_Mode_

Using STM8L051 ADC PD0, 3.7V~4.2V Li-Po battery, 1M+1M resistor to divde the battery voltage, 100nF capacitor to GND.If set PD0 floating input and halt, total current 40uA, if set PD0 push-pull output LOW, 10uA. But the drawback of output LOW is that I have to wait 350ms for the 100nF cap charging before a new ADC reading.Is there any method to reduce current consumption and remain floating input?

I am working on a project with the STM8S003F3. I need to configure the TIM1 to generate the following digital output signal on PC3:1. Turn PC3 output to High state immediately (<1us) when signal on PC4 input goes Low.2. After PC4 input signal goes High, wait 25us and then turn PC3 output to Low state.PC4 input ----------|__________|-----------------------------------------------PC3 outp. _______|---------------|-------25us------------|_____________I want to generate this signal without using interrupts and code, just by configuring the timers and the hardware must do the work without code.I thought using a complementary output with 25us deadtime would be OK and instead of an internal clock signal I would use the external signal from PC3? Is this possible?

Hi, I'm trying to reverse engineering a STM8 firmware. till now I can disassemble the binary firmware to get the assembler code using naken_asm : https://github.com/mikeakohn/naken_asmIs it possible to decompile it ? can anyone point me to some tools to decompile a STM8 firmware?thank you.

Hi =) I am designing a custom board with an STM8. I have a couple of STM32 Nucleo and eval board but looking at the schematics the ST-link only seem to have the SWD interface, not the SWIM.I do not have any STM8 board from ST have but I have another "cheap" ST-Link like the picture below. This one has a SWIM interface.My questions:1) Is this ST-Link enough to program my STM8?2) Which pins do I need to access on the STM8 - is it only SWIM and RST (+ VDD & GND)?3) Will the STM8 always respond to the SWIM pin when booting up? Because I see no "Boot" pin like the STM32's have. What if the pin is not configured as SWIM in the firmware?Th

It shows following error message when I program the board. Please find attached image for this. I am using IAR embedded workbench IDE for my development. Please help me with this as I am facing this issue since two days and not able to crack it.Thanks RegardsDeepak

I can't find any example programs for continuous mode. Well I found one but it doesn't even have a makefile to run it on my microcontroller.

I would like to use the STM8S005K6T6CTR in my next project. This is my first project outside of the arduino ecosystem, so sorry for bad questions(if any) .The MCU will be responsible for taking care of the following tasks:1) Driving a 4 digit 7 segment display2) 4 button water tolerant capacitative touch input3) Drive a buzzer4) Drive a relay5) Drive 6 LEDs6) A timer with 1.5% accuracy(possible without external resonator?)Thanks and Regards

I don't think the user manual is good enough for someone starting with ST MCU's. I have no idea how use the different cables with which boards, etc. Could not find any howto's. I bought this to replace a ST Link v2.

Hi,I'm new with the STM8S003F3 MCU.There is push bottom that connected to PD6.How the interrupt should be define?I'm using IARthanks

I want to design low voltage detect functionality like if voltage goes to xx volts mcu should reset

I have to design it for stm8afxx mcu

I used STM32 version of Cube MX and it was able to generated (a bit boated) peripheral and clock configuration code. I expected same from STM8Cube but it generates only a nonsense reports (which could be also created manually). While this tool is useless, is there any other tool or IDE which can generate the initialization code automatically? (don't suggest Arduino).

Can we have STM8 MCUs without the Thermal and Static Protection and make arrangements for the Black Dot ( as seen on Calculators ) for our Product's Board. Are there any other Solutions available ?

Hi there!I just want to open those workspace that I created before and find that all of them come with this error. I have not changed anything including path of libraries and workspac. Could someone point out how does this error come out and how to fix it ?Cheers~~!

Hi,i've installed STVD, download and install Cosmic Compiler for STM8 (free version with unlimited size). I've registered compiler and receive license file. I've forgot copy license file into lincence subfolder in cosmic installation folder. When i've started "build" in STVD, "LexNet Licence finder" popup and ask for licence file. It confuses me and i've reinstalled compiler again. After that i've placed recieved licence file into correct folder but "build" crash with error:#error cpstm8 C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8\Hstm8\mods0.h:1 FlexLM No such feature existsDoes it mean that i have wrong licence file ? (i've done reinstallation of Compiler, and used licence file recieved from previous installation ... on the same PC of course) Or it is some kind of deeper problem (using Windows 10 thus i am expecting problems :D ) ? Thanks to any advice how to solve this annoying problem.
