STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
In the QSPI chapter of G4series reference manual, we can confirm the support of external QSPI flash chip in mmap mode: "memory-mapped mode: the external flash memory is mapped to the device address space and is seen by the system as if it was an inte...
WHile debugging for a custom board this is what I am facing Break at address "0x1fff4080" with no debug information available, or outside of program code. This is the code that I am trying to run . What is the reason for this error and how it can be ...
Hi,We try to send an receive data to the external APS6404 RAM.Therefore we read the application note AN5050 and copy the function from page 55 (7.2.5).At first the function HAL_RCCEx_OCTOSPIDelayConfig() we cannot find in the library.What is correct ...
Hi all, I have already searched on the forms and in general did not find an answer to my problem, I will be very grateful to you for help.I need to create an output signal with a frequency of 100 Mhz as CLK in STM32H745. I used the Discovery Boards ...
I am testing the functions of STM32U575 and found the following issue.I simply wrote this in main(): while(1){ for(i=0;i<160;i++); HAL_GPIO_TogglePin(GPIOC, GPIO_PIN_11); } where i is defined as uint32_t.HCLK is set to 160MHz by using PLLCLK with...
Hello,I am using the STM32H743ZI2 controller with Cortex-M7 and firmware version 1.11.2 for a project where I am capturing camera data through DCMI and sending it over Ethernet using UDP to software that receives the data and builds a video stream.Ho...
Hello All, I am progressing toward my goal. I am bit banging a GPIO port every 2 uS based on a Byte buffer. I can not use SPI because I need to send a predefine number of bit that is not 8 aligned. So I use a timer and every UIF event I reset the GPI...
Hello,I am using ADC1 channel 1, 3 and 5. All these three inputs are connected to different sensors and I want to create a driver to read those sensors. The problem is that I don't want to read all input channels at once, I want to be able to select ...
Hi,I am trying to communicate with the MPU-6500 from InvenSense and the STM32F405 micro controller in SPI.I managed to read the WHO AM I. And seems to respond well with its value of 0x70.The problem I have is when I want to read the accelerometer and...
Hello,Am using STM32H745XI device same as the disco board and external flash on QSPI (MT25QL512A) single chip flash. IAR IDE is used for development. Though there are reference driver codes available for MT25QL512A but different controller is used. I...
