Helloon the a.m. device I use both ADC1 and ADC2. The initialization is identical on both. I notice that results fluctuate widely at ADC1 output and reasonably at ADC2 output.Grounding ADC1 input leads to 330-345 LSB.Vdda = 2.5V from precise external...

HelloI wonder if there is some example code available on how to use the Data EEPROM in the 8pin STM8L001J3.I did successfully work with the internal Data EEPROM on the STM8L051, but no success on the SO8. The address I used is 0x9BFB (in contrast to ...

Update and observation:On my HW, Vdda has a level of 2.5V from an external reference.ADC_IN1, once disconnected from everything and thereby floating, is sourcing (!) 2.9V with about 22uA of current. With 10k to GND, 220mV of voltage is sourced.This o...

Hello Janthanks for your fast reply. Package = QFN32, ADC input channels = channel 1, Pins 7 + 11HW is self-made.Voltmeter is connected as you describe: short leads directly on ADCs input cap.I checked on a third piece of HW, which, surprisingly, wor...

TO WHOM IT MAY CONCERN:Unlike all official examples show and all documentation implies, it is needed to address the Data EEPROM as if it was Program EEPROM. Hence the following code works:// Do this once, e.g. after power-up:FLASH_DeInit();FLASH_Set...
