In the RM0433 rev 7 in the Embedded SRAM chapter:AHB SRAM1 is mapped at address 0x3000 0000 and accessible by all system masters except BDMA through D2 domain AHB matrix. AHB SRAM1 can be used as DMA buffers to store peripheral input/output data in ...
Hi, I save my configuration structure to flash memory. It work. Data is stored in flash. But after unplug ang plug power memory page is writen by 0xFF.int eepromSaveConfig() { uint32_t error; uint64_t *configPtr; uint32_t address; FLASH_EraseInitType...
Sectin 6.3.1 of the reference manual says "During and just after reset, the alternate functions are not active and the I/O ports are configured in input floating mode." Floating inputs are bad. Our code will configure all pins appropriately immedia...
Hello,I'm doing some tests on the STM32H743 FPU (on a Nucleo, from Keil v5 IDE).I've checked that the FPU is enabled (register CPACR) and I've written a basic division by 0 test .volatile double test = 0; test = 1.0 / test;I checked the assembly code...
I have problems with power consumption. In standby power consumption seems to we be way over the documented ~1,97 uA. Current codes gives consumption around 300 uA. Is there something more that needs to be taken into account when putting the CPU to s...
Hi all,I'm using STM32G431, the opamp1 and opamp2 are set as follows:the generated codes: hopamp1.Instance = OPAMP1; hopamp1.Init.PowerMode = OPAMP_POWERMODE_NORMAL; hopamp1.Init.Mode = OPAMP_PGA_MODE; hopamp1.Init.NonInvertingInput = OPAMP_N...
Hello, im facing a problem when i try to program the chip, im using the eclipse ide and a cheap stlink debugger, the most common error is this:adapter speed: 24000 kHzadapter_nsrst_delay: 100Info : clock speed 24000 kHzInfo : STLINK v2 JTAG v34 API ...
How to change NRST pin to a interrupt input pin on the G031?
Hello to everyone. I am teaching an embedded system lab courses and this is our first year with a STM32F767ZI Nucleo board. We are at a point where we want to exploit the on-board temperature sensor to generate some input data. In our first experienc...
