Hi all,I am trying to read temperature data from MAX31855K over SPI, using STM8S103F3 on a breakout board.Development set up is STVD, STVP and Consmic compiler. And using STM8S Standard Peripheral library.Here is my max31855.h:#ifndef MAX31855_H #def...

Posted on April 14, 2018 at 07:52 Hi, I am trying to learn PWM generation with STM32F030F3P6. Generated code using STM32CubeMX. Basic PWM generation worked fine. Now I am trying to change PWM pulse width dynamically in while loop of mai...

Please note that I had switched to SDCC compiler. So, code may require minor changes if you are with a different compiler.

Yes, I had got that working.These are my update max31855.h and max31855.c:max31855.h:// @author: Junaid PV (http://junix.in) #ifndef MAX31855_H #define MAX31855_H #define check_bit(var,pos) ((var) & (1<<(pos))) #define MAX31855_SPI_GPIO_PORT ...

Hi Srikanth,Setting prescaler for TIM2 is different from TIM1. For TIM2 we are setting a number that will be used as power of 2 to get prescaler value. It is well explained in STM8S Reference Manual.So, to get prescaler value 4096, we need to set 12 ...

I think you can set 4096 as prescaler value.Default clock is 2MHz.So, (1/2000000) * 4096 * 15625 = 32Please note, Timer 1 has 16 bit prescaler capability and we need to set two registers TIM1_PSCRL and TIM1_PSCRH.Regards,Junaid
