DFSDM latency
We are using the STM32f413 with the DFSDM unit for converting the PDM stream generated from the external ADC. The clock is generated externally. We are using the OSR of 512 and sinc3 filter with an integration time of 8, a regular channel with contin...
Resolved! Working demonstration of I2C2 on STM32F412ZG - Busy flag errata?
I am currently bringing up a board with an STM32F412ZG.We are using the I2C2 peripheral on PF0 and PF1 and not having much luck.We can drive I2C1 and I2C3 without issue, but when trying to use I2C2 the busy flag remains asserted - even after forcing ...
Resolved! How to change the linker file for STM32H743 to support using the whole 1 MB of RAM for the code execution?
Here is the content of stm32h743xx_flash.icf:define symbol __ICFEDIT_region_ROM_start__ = 0x08000000;define symbol __ICFEDIT_region_ROM_end__ = 0x081FFFFF;define symbol __ICFEDIT_region_RAM_start__ = 0x20000000;define symbol __ICFEDIT_region_R...
For STM32F7x 14pin JTAG on target board and compatibility with ST-LINK/V2
Hi,On my target board I have implemented 14 pin JTAG interface as in STDC14 CN1 connector. Can I use ST-LINK/V2 debugger to flash and debug the controller..?The controller part is STM32F750V8. Please help with this.Thanks,Dhara
Question about access internal flash on STM32H7
My codes are stored on bank2 and I am trying write some manufature data into BANK2 (sector 14) of internal flash.Howerver it always fail in erase stage dut to the flag of PGSERR is raised.If I change to write data to bank1 (sector7) this symptom not ...
How to make sure ADC reading get correct values in a single conversion done in a for loop?
I have a code that reads 12-bit ADC value from PA1 of STM32F0. I manage to get the voltage reading right when I just get it from a DC voltage but with an AC voltage produced from an op amp, the values that are stored from the reading consists of a lo...
STM32f469 - ADC accuracy
Hello , We are interfacing Analog Accelerometer with STM32f469. Attached here ADC interface hardware and ADC firmware (configuration) for your reference . Problem is Accuracy with ADC values. The ADC values are varying approximately 30mV . Can anyone...
STM32 internal ADC for reading temperature.
/*I want to read stm32 temperature using ADC1 with timer 2 configured. I am getting temperature reading as 60 degrees when I configured ADC1->SQR3=16; and -275 degrees when ADC1->SQR3=18; Is any thing wrong? */ #include "stm32f4xx.h" //...
