USART RTS vs CTS
Hi,I would like to connect my Sequans GM02s iot module to my Stm32L4 mcu via uart. Would the RTS Signal from the iot module connect to the CTS signal from STM32L4 or vice versa?

Need a I2C driver to communicate STM32F101R8T6 to a MPU
Hi,I have a STM32F101R8T6 based I2C slave device and now I want it to interface to a TI based MPU - AMX625 which is running on Linux OS.My question - Is there any generic I2C driver available to communicate from AMX625 to STM32F101R8T6? Thanks.
STM low price 4xI2C, 48 pin
Hello,I am looking for STM with the following features:- 48 pin (could be 64 pin only if BGA)- 4 I2C interfaces- 1 ADC channel- most important: lowest price possibleCould somebody suggest several P/N I could check? Adam
ETH_REF_CLK (PA1) noise / crosstalk on ADC1_IN0 (PA0)?
Hello,Has anyone seen ADC noise generated by the 50 MHz RMII clock (PA1) affecting the measurement on ADC1_IN0 (PA0)? (approximately 100 codes in 4096).If so does anyone had a fix to suppress it?All other ADC channels used do not have the same level ...
Usage of decoupling capacitor in STM32H503KBU6
Hi, I am currently using STM32H503KBU6 MCU (32 pins). For my project the space in PCB board is critical. I have placed a LDO, Level translator, voltage supervisor and along with their associated passives in a 10mmx16mm PCB board. Now I still nee...
