Hi leo,

In STM8l15x_StdPeriph_Lib you can find a set of examples (USART, ADC, Timer...):

Download it from:

Sorry was not that clear.

i mean, its default port use was

PC2/[USART1_RX](3)/LCD_SEG22/ADC1_IN6/COMP1_INP/VREF_OUT

and

PC3/[USART1_TX](3)/LCD_SEG23(2)/ADC1_IN5/COMP1_INP/COMP2_INM

and in my application I want to use this as my USART

PA2/OSC_IN/[USART1_TX](3)/[SPI1_MISO] (3)

and

PA3/OSC_OUT/[USART1_RX](3)/[SPI1_MOSI](

Hi leo,

You find in the product reference manual of stm8l15x, go to system configuration section.

link for download: http://www.st.com/stonline/products/literature/ds/15226.pdf

If you are usign the firmware provided by ST, you can use SYSCFG_REMAPPinConfig() function.

Good luck,
