STM8L050J3 Bug?
Hi,I am experiencing a serious problem with STM8L050J3.Due to an unused pin configuration of port A (PA1..PA7) then excluding PA0 used as SWIM, in order to check for any difference in current consumption, I have configured Port A with the following c...
How to synchronise 2 PWM in STM8S003F3?
I need 2 PWM signals each with different frequency and duty cycle. So I'm using TIM1 and TIM2 for this. But these PWMs are not synchronised. Please help me on this.
With STM8S005C6 How to program ADC Interrupt with a range of ADC_WG with continuos mode, with the scanning?
Hello, I would like help to have configurating the ADC peripheric to use it in continuos mode with three channels of the micro stm8s005c6, could you hand me an example made with the FWL from ST? Im using it right now with no success.I have being read...
Why getting such error though code looks error free ? #error cpstm8 ..\..\src\main.c:350(0+6) misplaced local declaration #error cpstm8 ..\..\src\main.c:411 static function monitor_express_open_input_button undefined

Can JTAG pin 19 VDD (out) be connected directly to SWIM VDD (sense) to power STM8 MCU's from ST-LINK /V2 when programming?
It has been weakly suggested in other threads, but I would appreciate a firm confirmation. Does anybody have first-hand experience doing this?Is anything else required? For example connecting the grounds of the SWIM and JTAG? (Hard to guess the corre...
How to connect st-link v2 with Tag-connect cable
HiI plan to program my MCU using a Tagconnect cable. I haven't bought the Tagconnect cable yet, nor the st-link v2, and I would like some recommendations.Is anybody using this setup? What are your thoughts?It also seems there are different versions o...
Can SWIM interface also provide power to target board while debugging ?
On STM8 controller the 4-pin SWIM interface has a power pin (pin#1) that has been indicated to sense the target voltage. Can this pin be repurposed some way to drive the target board ? So SWIM interface provides output power so the target circuitry d...
Another problem with the problematic STM8L050J3
Hi there,I have made changes to the firmware and , via ST-Link V2, I would like to reprogram an STM8L050J3, which I had previously programmed with the Active Halt function enabled, but SVP does not allow it and responds with this message as the attac...
