First RAM location in page zero inaccessible - returns fixed data. Why ?
I have a minimal development board with a STM8S103F, ST Visual Develop, and ran into the following :Location zero ($00) is inaccessible using direct adressing modes. Reading returns fixed data, and writing has no effect. Using the debugger it is poss...
STM8AF528 flashing issue
Hi there,If I am flashing the .s19 file using st visual programmer I have observed that there is a flash memory corruption. But If I am flashing this with visual developer I am not facing any issue.Can anyone tell me is there any alternate SW tool fo...
Resolved! STLUX adc trigger
I am trying to configure an STLUX285 SMED to trigger an ADC measurement but am unable to find the documentation of the registers required to do this.RM0380 claims "SMED as ADC trigger source" in section 21.16."AFR_IOMXP2" is supposed to have a bit ca...
How To get internal RTC time using STM8L050J3
Hi All, We are using the STM8L050J3 chip and trying to get time using an internal RTC with LSI. We are getting some responses but are not sure what it is. Here is our result (TIME: 3108:4877:2644) and code. We are using the cosmic compiler. Could an...
Cannot compile code without stm8_interrupt_vector.c being brought into my project despite removing it from project.
I am trying to implement the "Delay" function from timing_delay.h / timing_delay.c that comes with STM8 example code. In order for the delay to work, you need to add the function "TimingDelay_decrement" to stm8l15x_it.c in order to decrement the time...
Resolved! STM8L050J3: SWIM and USART TX on same pin?
Hi. I am designing Schematic for STM8L050J3 chip. In that, pin1( first pin) , in datasheet they mentioned as SWIM in port A0 of pin1 and USART TX in port A2 of pin1. I want to use this pin as SWIM for programming as well as USART for data transmissio...
