NUCLEO-F446RE Modbus Slave - Writes Work (LED dimming via PWM), Reads Fail with Truncated Exception Responses

The IssueI'm using **nanoMODBUS** (slave mode) on NUCLEO-F446RE via USART2 (115200 baud, 8N1). The slave exposes two holding registers:- `0x0000`: Potentiometer value (read-only) → `usPotValue`- `0x0001`: LED brightness (read/write) → `usLedBrightne

How To Change PWM Frequency With Only The Prescaler

Hello,I have inherited some code where a 5kHz 50% PWM is output in center aligned mode using TIM1. CK_PSC is 275MHz, CK_CNT is 137.5MHz (I think) because PSC = 1.The pattern output matches the implementation: The yellow trace is a GPIO pin that is

STM32WL5MOC PA Damage without antenna?

Hi, If you were to remove the antenna from circuit and transmit on the STM32WL5MOC, would you damage the internal rf power amplifier that transmits the signal due to the signal being fully reflected back to the output of the rf amplifer? Best Regards
