STM8S003F3 I2C Slave Not Working - Troubleshooting Assistance Needed
I'm trying to operate an ESP32 in Arduino as an I2C master and an STM8S003F3 as an I2C slave.* ESP32 I2C master source code (slaveAddr = 0x30)void i2c_sendDataToSlave(TwoWire &i2c_device, uint8_t slaveAddr, uint8_t* slaveBuffer, size_t slaveLength){i...
stm8 using AWU/HALT/EXTI
I am building time lag switch- i have at42q1010 touch ic connected to PA3- i have stm8s003f3 mcu- Using latching relay to conserve power- timeout is my pot value- Exti on at42q1010 rising edge exti_cr1 =0x01; ( the ic reads low when no touch and when...
Resolved! STM8S103 Timer TIM2 timing
Hi,Using ST Workbench debugger my 16-bit timer TIM2 (china bought) overflows each 16 seconds as the prescaler is set to 10. With an 16MHz internal clock divided by 2^10 (1024) the timer should overflow theoretically each 4.1 seconds. Prescaler 9 take...
