You are right it's a bit messy I will report this and request an update to the Ans and documents. The rule is ,depending on the MCU, you put a 2.2nF per Vcap in parallel, if you have a 3rd Vcap pin you just connect it to the other Vcap pin...
In the STM32CubeL0 you downloaded, you can look into the STM32CubeL0 /Projects /STM32L0538DISCOVERY /Applications /TouchSensing / folder. There's an example there. This can help you start on your project.
Hello WPazH,The STM32L4+ or any STM32 embedding the TSC touch sensors doesn't support mutual capacitance. The TSC is not a very robust solution in terms of moisture and water resistance indeed.Regards,Stassen
Hi STE_Michael,You are right it is only a software delay and this allows that all capacitors to be completely discharge.The formulaTSL_Globals.DelayDischarge = (uint32_t)((TSLPRM_DELAY_DISCHARGE_ALL * (uint32_t)(SystemCoreClock /1000000)) / 72); is ...
