Bus fault when running ARM DSP functions
1. I am implementing a custom extended kalman filter function. The program on running hits HardFault handler on the 4th iteration (prediction function).2. Cortex-M4->CFSR = 0x8200 (BFARVALID=1)3. BFAR holds : 0xa5a5a5a5I am not able to understand whe...
CAN FILTERS
Posted on November 11, 2015 at 17:50 Hi every one, especially Mr.Clive, today i have problem with CAN FILTERS i want to allow all IDS from 100 to 1FF in other words block all messages after 0x0200 here is my code, Please help me, Thanks in...
STM32F103RB and LRWAN1
I bought STM32L073RZT6 and LAWAN1 expansion board, will STM32F103RB and LAWAN1 be compatible?
STM32L4xx (and maybe others) EEPROM emulation library bug with single-bank flash mode
When used on STM32L4xx platforms (and possibly others), with flash configured for single-bank mode, the EEPROM emulation library (https://www.st.com/en/embedded-software/x-cube-eeprom.html) miscalculates flash sectors which causes silent erase failur...
Resolved! STM32L45 I3C support?
Hi, I am using the STM32L45 series in my HW and I wonder if it can support I3C protocol?If not, is there another compatible MCU you would recommend?Thanks, yy
FW upgrade over I2C from XMC/Infineon chip, intermittent failures (NACK, busy), ROM bootloader fail?
I'm trying to do a FW upgrade on the STM32F427IGH6 chip, having an Infineon XMC4800-F144K2048 chip as the master and the STM chip as the slave. They're connected via I2C; I've confirmed that the lines are connected properly, as I'm able to send data ...
No device found on target
I can't seem to connect to my STM32F401RCT6. This is the schematic below and all the jumper wires are working. Can anyone spot the error?When i try to connect to it i get the message 'No device found on target'
LSI clock stability vs. normal and low power voltage regulator
Hi,The LSI clock speed changes by 200..300Hz when the voltage regulator switches (ie., when the MCU enters stop 1 mode). Since I calibrate this clock to the 32MHz HSE in running mode (with the normal voltage regulator), it causes an inaccuracy in sto...
