Using indications instead of notifications with BLE
Hello,I have a question regarding implementation of BLE on proteus and nucleo boards.I am struggling to understand how confirmation of indication is processed by the server (and also how does client provide this confirmation). There doesn't seem to b...
Hex or bin with multi-firmware
My solution have more than one project, each project program in different address. exp: bootloader(0x08000000, 64K) application(0x08010000. 448K).How can create an hex or bin with these two ?
connect two stm32 board using uart
Hi, may I know how to connect two stm32 board using uart?Im using nucleo g071rb to transmit the data to STM32H750-DK. So basically i just want to try simple application using serial but it not successful.so what i want to do Nucleo G071 transmit data...
Waveform Non Pin Timer GPIO STM32F429IGTB
Hi All,I want to generate digital clock/waveform at non timer pin STM32F4219igtb, let say using pin PORTD.5 and synchronize with several GPIOs using DMA. the purposed to drive the multiple HUB75 port.Currently i'm succeed to drive the clock pin using...
How to toggle GPIO using the "PWM Generation No Output" Timer mode ?
I have a use case where I need to toggle a GPIO based on a PWM waveform. Since the GPIO chosen doesnt fall in the PWM timer pins, I have to toggle the GPIO in some other way. I came across the timer mode "PWM Generation No Output" mode. I am thinking...
Resolved! SPI slave interrupt is slow in STM32F767
I am working on SPI slave at NUCLEO-F767ZI.I am using the interrupt and LL library. This is the RX handler:void SPI1_Rx_Callback(void) { if (LL_SPI_GetRxFIFOLevel(SPI1) > LL_SPI_RX_FIFO_HALF_FULL) { // this is only for break point ...
Resolved! STM32H7: Multiple Push Button Interrupts
Hello,I am looking to implement multiple push buttons (7, specifically) that are used to turn certain features ON/OFF on a front panel. For example:PB1 = LED ON/OFFPB2 = DC Power ON/OFFPB3 = AC Power ON/OFFetc.My current plan for my custom board to d...
I have a button connected to STM32F405. I am using external interrupt with the button. Inside the callback of the external interrupt I am sending a command to retrieve some data from another microcontroller as a loop. But I am receving only data once.
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if(GPIO_Pin == GPIO_PIN_10) { for(volatile int j = 0; j<3000; j++) { char Txbuffer = "Read\n"; HAL_UART_Transmit_IT(&huart2, (uin...
Using two STEVAL-IDB008 V2 boards, neither will connect to the BlueNRG GUI v4.3.0 or v4.4.0 application.
When first received, they both did connect to the BlueNRG GUI app, but with more tests, they no longer will connect - they show up as not detected. However, both boards connect and program OK with the BlueNRG-2 Navigator v 3.2.2 application. Both boa...
