Hello all, I'd like to know if I'm making full use of the FPU on an F730 using SW4STM32/Eclipse. In project properties i set floating point hardware to fpV5-sp-d16 and the ABI to hardware. I also define __FPU_PRESENT & ARM_MATH_CM7 and set the libra...
Hello everyone, so what I’m going to do is displaying the value of the temperature on the LCD of the STM32F413H-Disco with a PT100, i wrote this code:int value;char getvalue[20];...MX_ADC_Init();HAL_ADC_Start_IT(&hadc1); (I choose Interruption becaus...
Is there an alternate function that needs to be disabled for this to work by default? The datasheet footnote says "SPI2/I2S2 and I2C2 are not available when the Ethernet is being used." Is the Ethernet enabled by default and how do I disable it or pr...
I think I have proven now through tests that the and is clearly "YES". But, I'll still put this is as some awareness raising anyway. It might not be immediately obvious that an interrupted task can override the value of an interrupting task. Also, I'...
Hello,I'm a bit confused about how memory addressing and byte alignment works when using two QSPI FLASH memories in dual flash mode.Accordingly to AN4760 paragraph 2.2.4, in dual flash mode addresses are "splitted" across two banks by sending even ad...
Hi,Sorry for my stupid question but I am always in doubt when I give the priority in the NVIC table for DMA, UART, SPI, Timer, ...Is there a rule like for example set all DMA at 0 ?How to know what peripherals must have the highest priority and how ...
Dear Members,I have 4 devices on I2C 1, 2LCD s and 2 Sensors,I tried to init 16x2 I2C LCD, it seems that it blocked all the process,Is it because of 3.3V databus ? Does it need 5V databus?HAL_StatusTypeDef LCD_SendInternal(uint8_t lcd_addr, uint8_t d...
Hi ,I am using 2 F103rb NUCLEO. My code works fine in LoopBack modeBut when I use in normal mode, the TransmitMailbox status is pending I cannot receive on the other boardThe transceiver I use is TJA1050I do put resistor between CAN H and L , 120ohmM...
I am using STMG32G070RB8TX for Programming the device is detected in TS link Utility but when i compile the compiler throws an error below is the description of the error.Error in final launch sequence:Error in initializing ST-LINK device.Reason: (25...
