Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
Hi, everyone. I have been working with STM8S, i am did not work with this microcontroller before, i have some questions about ADC (i am using STM8S103F3). 1) The first problem that i had was about the values read, i am initialize the peripheral for w...
Hello everyone,I'm new on STM and I find myself having to use the STM8 in a linux environment and I saw that ST provides its IDE only for Windows.I would like to know where to find an IDE + software programmer (using ST-LINK V2) where to develop soft...
The "STM8S standard firmware library" is referenced in UM0834 for STM8S-Discovery. The library examples were well organized according to the descrription and included everything for the quick start. There were timers examples, ADC, SPI, I2C, UART exa...
void Init_ADC(void) { ADC1_DeInit(); ADC1_Init(ADC1_CONVERSIONMODE_CONTINUOUS, ADC1_CHANNEL_5, ADC1_PRESSEL_FCPU_D2, ADC1_EXTTRIG_TIM, DISABLE, ADC1_ALIGN_RIGHT, ADC1_SCHMITTTRIG_CHANNEL5,DISABLE); }void ADC_Read(unsigned int MV) { ADC1_...
Hello all. There are 9 sources of reset possible in STM8AF52xx according to the reference manual.They are :External reset through the NRST pin• Power-on reset (POR)• Brown-out Reset (BOR)• Independent watchdog reset (IWDG)• Window watchdog reset (WWD...
IRET returns to nowhere from wakeup timer ISR as soon as programmable alarm interrupt is active!Here is the STVD screen where programmable alarm and wakeup timer interrupts are enabled and wakeup timer ISR is just about to end. In the memory window a...
I am analyzing the UART data frame of an outsourced device that uses the STM8S105 MCU. The data frame specification is:* 1 start bit,* 8 data bits, * 1 parity bit,* 2 stop bits.Therefore I expect a data frame as in the below Figure 115 from the STM8 ...
Code shown in details. I am guessing something is wrong with clocks - this doesn't make sense though since tx is working just fine. I see signals just fine on the scope. Both tx and rx are high during no transmit. Clocks and initialization code shown...
