I am using Nucleo-f446re and communicate with a server trought a GPRS telematic device ( the communication with the telematic device is through uart protocol). My average firmware size is 35kB. I can safely transmit the hex file to the MCU but I ne...
I want to wakeup from standby-mode in less than 20msec.I want to wake up from standby-mode in less than 20 seconds using Periodic auto-wakeup, but I can't wake up below 22 msec.Could you tell me if there is any good way?The following HAL driver is us...
Hello I am trying to perform FFT on real data sampled with ADC However, first I need to perform it on test data that I generated inside my code to verify it would workI set parameters: frequency, buffer size, sampling rate (buffsize 512)then I gener...
Hello, I have an project with STM32F103 and using CubeMX drivers. I successfully setup the driver, but I have a problem when trying to send out from pc packets biggest than 64 bytes. (64bytes is the enpoint buffer & max packet size). On PC I'm using ...
I'm using STM32F4 Discovery board and its expansion board for SD-card interfacing. I'm using SD-cards with DMA2 and STM32CUBEIDE FW_F4 V1.24.2Before pointing out error I want to attach below link as a reference which I've used in my code -https://co...
Hello,I am developing a simple GUI for a custom board based STM32H750 MCU.My requirements are the following:Both application code/data and touchGFX images/fonts are stored in and external QSPI (0x90000000) The entire application must be executed in t...
Hi, I'm trying to connect to my MQTT Broker with STM32F7 Discovery kit.Firstly, I used MQTT Client in LwIP stack. When I call this function: mqtt_client_connect()the Error return ERR_RTE, mean Routing Error /** Routing problem. */ ERR_RTE = -4...
High Level Problem Description:STM32F4xx: Produced on STM32F427IIHxWhat happens:When SPI as master, full duplex, 8 bit & ~1MHz clock speed and doing longer transmissions (e.g. 10 - 60 bytes) using interrupts the current implementation in Keil::STM32F...
Details:MasterMode: HAL_I2C_MODE_MEMClockspeed 400kb/sSymptoms:In Master-MODE_MEM after memory address has been sent a repeated start should be sent (in I2C_MemoryTransmit_TXE_BTF()) before the switch to read. However if the ISR is handled quickly th...
