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...
