Hi all, I’m reaching out for assistance with integrating an ST485ABDR transceiver with an STM32F723ZET6 microcontroller. I have encountered issues while trying to control an RS485 stepper motor driver using this setup; however, I am able to communica...
Hello, I would like to know if anyone has already encountered this problem. I have an LPTIMER configured with an ARR Match interrupt at 100ms I also want to enter my interrupt every 10ms so I added an interrupt in compare mode at 10ms.I have 2 questi...
Hello,For my project I am working on two nucleo board H743ZI2.Unfortunately, during an experimentation one of the boards ceased working (LD4 and LD6 red). Maybe a short circuit, I don't know.Anyway I tried to purchase a new NUCLEO-H743ZI2 but it seem...
Hi,Im using threadx, in that i have defined a task in which i initialize my external flash memory regions i have a 116 byte structure which contains memory informationwhen i use this structure locally i get a never execute hardfault error where as wh...
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.
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
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 ...
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...
Hello, how to know ram memory usage using debugger, to check where memory is used. This is without FreeRTOS or CMSISI know freeRTOS has TaskGetStackHighWaterMark()
I'm using STM32L486 at 2.5V.The MSI auto calibration feature (aka PLL mode) is crashing at cold temperatures with specific usages of Stop mode. When it crashes, it drives MSI to its minimum frequency for the selected range. For example, the 24 MHz ...
