Posted on July 07, 2018 at 04:41Hi, I'm having trouble reading a register in a slave through I2C communication. Slave: bq25895 http://www.ti.com/lit/ds/symlink/bq25895.pdfIn main:while (1){ HAL_StatusTypeDef status = HAL_OK; uint16_t return_val...
the DAC1 out1 working fine as programmed bt DAC1 out2 is not. Is it due to bridge18 A4 to D4, should I remove bridge. I try setup D4 as Analog and Digital IN and does not helped. Is STN32L$#@RC damaged on out2?
Hi,I have a single adc channel where i read the input values through polling, but it always outputs the max value or almost max value (~ 65280+) as long the input voltage value is greater than zero (v0.5+ ). i configured VREF+ to internal voltage ref...
The 'F427 (437/429/439 "BigManta") is pretty much completely backward compatible, meaning, that a reasonably well written 'F405/407 program (i.e. which does not touch the bits reserved in 'F405/407) binary will run unmodified in the 'F427. There are ...
Hello,I am trying to erase/flash program an external W25X40CLSNIG flash chip with various STM32L4xx host chips using SPI protocol. Up until now I have been referencing STM32l4xx_hal_spi.c source file for ways to perform such a task but was curious if...
I am using ADC1 and ADC2 of STM32F446RE, which are operated under the following conditions;Dual ADC modeRegular Simultaneous modeExternal triggerI can correctly read the converted values through ADC1->DR and ADC2->DR.However, I can not read the corr...
The SWO/TRACESWO with Instrumentation Trace Macro cell should be able to extract information about what instructions or addresses were executed.However I still can't find the right tool to do it.It would be enough for now to show the addresses the PC...
Hi all,I would like to boot a RAM image. A simple bootloader in flash reads in a linear binary from external spi flash. The RAM image works fine if I load it directly to (AXI)RAM (with JTAG).But when loaded by the boot loader, it does not work (loops...
------------------------------------------------------------------The init of RCC was correct. The SystemCoreClock variable dont reflect the new frecuency changes still "SystemCoreClockUpdate" is called.-----------------------------------------------...
Some time ago I tried your STM-STUDIO: I found it very rough and can only be used for laboratory debugging.Why don't you plan to build a more flexible debugger that can then be used by the end customer to view internal data or change parameters?If yo...
