i try to get spi work in custom board in stm32h743VIH mcu. I'm using mco1 output clock to supply master clock to external adc converter and spi2 to read data. I want to use system with 1.8v supply voltage. I'm using stm32Cube ide to generate code. Fl...
Hello,I am using DMA for one SPI slave with which requires SS Pulse mode.Now I want to use two or more slaves is it possible to use HW SS with multi slave "I think No"is it possible to use HW SS for 1st slave and SW emulated SS using GPIO for the o...
HI I USED STM32F303RC ADC1 ADC2 ADC3 ADC4 ONLY PROBLEM ADC 3 USED ADC3_CH1 FOR REQULAR AND CH3 FOR INJECT BOU INJECT READ IS WRONG FOR TEST CHANGE REQULAR TO CH5 AND INJECT TO CH5 AGAIN REGULAR READ CORECT BOUT INJECT READ WRONG THIS MY CONFIG ADC __...
I 'm making a voltmeter - amp meter, this one...I 'm using an STM32F030K6T6.But when nothing is connected to the input, instead of outputing 0, the ADC gives me a value around 980.VDDA is tied to VDD.Boot0 is tied to GND.These are the ADC 's settings...
I have a program for which I would like to enable link-time optimization. However, once I pass the -flto flag to the compiler and linker, I get two linker errors, one complaining about multiple definition of _exit and undefined reference to _sbrk. I...
I did set up a basic STM32_CubeIDE project with 3 USARTs.When the PB11 Pin (USART3 RX) is connected to the communication signal, the signal is corrupted to a high signal level of 2.6V and a low signal level of 1.7V. This also happens also, when I con...
This is my code.GPIO_PinState boButton_state ;printf (" Hello �?� Cruel �?� World \n"); while (1){boButton_state = HAL_GPIO_ReadPin ( B1_GPIO_Port , B1_Pin ); HAL_GPIO_WritePin ( LD6_GPIO_Port , LD6_Pin , boButton_state );HAL_GPIO_TogglePin ( LD3_GPI...
I need to dynamically change waveforms on a PWM output on an STMF030 MCU.See it as a poor man's alternative to a signal generator using a DAC.It will be used to generate modulated audio waveforms.I am using DMA to lookup (a sine) waveform via a circu...
I want to know: how many analog input pins are there in each board. which board is good at taking data from sensors continuously which would be better for USB communication with raspberry pi or is there some other boards which is good at taking analo...
