How to detect external reset reason through NRST in stm8?
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...
Resolved! Not possible to use programmable alarm and periodic wakeup functions simultaneously on the STM8L051F3 MCU?
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...
Resolved! STM8S105 UART (async), data frame with 1 unknown bit after 2 stop bits
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 ...
Why is my uart rx not working?
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...
can i use the _classb_checksum160 function on STM8AF5288 MCU for flash integrity check at startup ?
i had received this function from the ST Micro self test evaluation package for MCU STM8S207RB
