Solved

I am trying to figure out SPI communication between two microcontrollers: I have an STM32H755 Nucleo and a Nucleo G47RE. I tested basic communication by shorting MOSI and MISO on both boards separately, and it works in full duplex master mode. Both core are running at 100Mhz The G4 is the slave and it is receiving some data, but it is corrupted. What could be the potential reason?   These are my configurations and code: /****************************************************** Slave side****************************************************/   // Main Function int main(void) { HAL_Init(); // Configure the system clock SystemClock_Config(); // Initialize all configured peripherals MX_GPIO_Init(); MX_SPI2_Init(); MX_SPI1_Init(); MX_LPUART1_UART_Init(); MX_I2C1_Init(); // Start SPI reception in interrupt mode HAL_SPI_Receive_IT(&hspi1, rx_buffer, sizeof(tx_buffer)); // Infinite loop while (1) { // #define FULL_DUPLEX #ifdef FULL_DUPLEX HAL_SPI_TransmitReceive_IT(&hspi

Hi, I want to generate a 1 microsecond (1 µs) timer interrupt on the STM32G0B1RCT6 microcontroller using its internal clock(16MHz). I am currently using a 16-bit timer to achieve a 5 microsecond delay, but I cannot achieve a 1 microsecond delay. My question is: what is the smallest achievable delay in microseconds for a 16-bit and a 32-bit timer?

Hello,I'm trying to find out why nx_tcp_client_socket_connect is returning 0x38. This error code is not listed in documentation. Because of this, there is no ARP packet being sent. static VOID nx_app_thread_entry (ULONG thread_input){UINT status;status = nx_tcp_socket_create(&NetXDuoEthIpInstance, &client_socket, "Client Socket",NX_IP_NORMAL, NX_FRAGMENT_OKAY, NX_IP_TIME_TO_LIVE, 200,NX_NULL, NX_NULL);status = nx_tcp_client_socket_bind(&client_socket, 45450, NX_WAIT_FOREVER);status = nx_tcp_client_socket_connect(&client_socket, IP_ADDRESS(192, 168, 15, 16), 45450, NX_IP_PERIODIC_RATE);}

Hi, I am trying to communicate via FDCAN with a board equipped with a STM32G0 by using this library https://github.com/owennewo/SimpleCAN I already tested it successfully with both STM32H743 and STM32H723 but I am having troubles with the G0  When I try to send a message from the G0 I get error code 200 back from the serial logs Does anyone have an idea of why is this happening?

Hello,I am using STM32H745XIH6 controller Board, and a display resolution of 480 x 480. In my application I need to move the box widget to a particular x and y positions. The thing is we need a smooth movement of the box at  a particular position. In the interaction 1, Am selecting the "Screen transition begins" in the trigger, and the action to "move the widget i.e. Box 1" and the "y value(ex: 300)" for the position to move the box.And the box moved to the particular position that I have mentioned. but when I have added another interaction after some animation delay to move the same widget to another position by changing the value in interaction 2(y value changed to 100) then the box directly goes from '0' to '100' rather than changing from '0' to '300'(box will move downwards first) and '300' to '100'(box will move upwards next).Could you please help me in this regards?

does MEMS studio support STEVAL-STWIN KT1B board ; cause according to the UM (https://www.st.com/resource/en/user_manual/um3233-getting-started-with-memsstudio-stmicroelectronics.pdf) only STEVAL-STWIN KT1 Hardware compatible (not with full/reduced sensor evaluation) just for algobuilder functionality.

Hello,After installing version 1.15.1 of CubeIDE, the labels in the column headers 'System Core/NVIC/Code generation' disappeared. It's not a big issue, but it's a bit annoying.Look at the below image.

I would like to show some texts on the display when running the "debug" build configuration, but not when code is compiled for the "release".How to?TouchGFX (4.23.1) generates the code and STM32CubeIDE (1.14.1) builds and flashes the project.

I am designing to mount LPS25HB on the board.Communication is I2C.Please help me with the connection of Pin 7 (INT_DRDY).Is this pin an open pad? Or does it need to be connected to GND?

Hi, I'm using a STM32F407VGTx, trying to use MQTT on this microcontroller.I first made a test program on a NUCLEO dev kit (also a F4 controller) and it worked.Now I get an error and it doesn't want to connect to my PC which is the broker. I have tried the following things:- I have made sure my firewall doesn't block port 1883 en 8883.- I can ping the controller.- I made an extra init flag to make sure that the init code runs first before trying to subscribe or connect to anything. I got the following error first: ERR_RTE = -4 which is a routing problem.But his has changed and now I get:Assertion "mqtt_sub_unsub: client != NULL" failed at line 1183 in ../Middlewares/Third_Party/LwIP/src/apps/mqtt/mqtt.c(so I'm not sure if the previous error is fixed) I'm not immediately sure what the problem can be. For more context i'm using freertos and have given the task a stack size of 256 words. I have included the code from the task. Anyone have any ideas? Kind regards,&n

Hello,In the RM0399 58.1 it is mentioned that EMMC is supported up to Version 4.51. I want to use the part  IS22TF08G-JCLA2 which supports a number of emmc interfaces up to 5.1 are these parts compatible? 

Hi,  For my application I need the following, I want to store variables in Flash memory, in order to preserve the data after a Hardware reset. My approach is as follows: 1.) Modify the linker script to keep a page of flash memory outside of the program memory. -> Outcome, This I did correctly as seen below, My flash memory boundaries in the RM and Datasheet for my MCU is shown below: So, we can see that I have 2 pages free (4 K), where the program will not be stored. [The RAM is in the SRAM, which is not in the flash segment of the memory , so this is leaved as is]. 2.) Modify the Variable which loads the vector table into flash. -> Outcome: This is shown below ,found in the system_stm32g0xx.c file.  The questions:With the above facts in mind. Without even  touching the empty blank flash pages. My application after a hardware reset does not run, my code does not run after the controller experienced a hardw

Hope all is going well. I'm trying to ping STM32H743ZI NUCLEO 144 using LWIP middle-ware. Code generated by CubeMX. Configurations: Set the HCLK to 400 MHz Enabled the CPU ICache and DCache (under Cortex_M7 Configuration) Enabled MPU (Region0, Region1 & Region2) Enabled LWIP Selected LAN8742 as the Driver_PHY (under LwIP>Platform Settings) DHCP disabled (IP, MASK: 255,255,255,000 , Gateway: Modem IP) RTOS disabled LWIP_HTTPD (LWIP_HTTPD_CGI & LWIP_HTTPD_SSI enabled) LWIP_HTTPD_MAX_TAG_NAME_LEN set to 16 ICMP enabled (LWIP_BROADCAST_PING and LWIP_MULTICAST_PING in LwIP Key Options>IPMP Options). Code Generated for Keil V5 MX_LWIP_Process added to the main function in While loop. while(1) { MX_LWIP_Process(); } I don't know how should I configure the CubeMX or change the generated code to be able to ping my board.sir can you please share the working code please :folded_hands:

It's not mentioned in the Databrief or AN4894 or elsewherehttps://www.st.com/en/embedded-software/x-cube-eeprom.html So it's AN4061 instead ?

Posted on December 06, 2017 at 18:06Hello,I'm using STM32cubemx and I have created a project using UART in 9-bit configuration. The code is generated and I can find the 'HAL_UART_Transmit' function but the pData parameter is a 8-bit pointer:HAL_StatusTypeDef HAL_UART_Transmit(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size, uint32_t Timeout)pData should be a 16-bit parameter. I cannot understand how can I send a 9-bit data with this function. Is it a bug in STM32CubeMX?ThanksIBRA

Hello Friends, I am looking forward to select the STM32 series micro-controller for my application i.e. STM32F407VET6 with Ethernet PHY interface of LAN8742a. I need to support the BACnet/IP on it. Can you confirm the below queries: 1) Does ST have any BACnet stack implementation for STM32 series controller?  If yes, Is it paid or free version? 2) Does the  STM32 series controllers support the opensource BACnet stack for BACnet/IP? 3) Does any other microcontroller from support open source BACnet/IP stack? if possible, could you suggest a demo example of stm32 with BACnet IP stack ? Kindly check this and let me know. Hoping to hear from you soon   Thanks and Regards, Prajwal Bhuse design@avyannatech.com

Hai All, We can configure a GPIO pin either as a Push-Pull or Open-drain configuration. Can anybody explain briefly, what are the applications of Open Drain configuration?

Hi all Thanks in advance.Can some one help me to select an stm32 chip which have 4 PWM channels , 4 analog out and in 3X3 qfn package? I attached a sample product. Kindly help me to select some more similar products.

To implement a "bridge" devise between two independent CAN buses, the STM32F105R8 chip was chosen. From the specifications it follows that it has 2 CAN buses, but going deeper into it I realized that they share a lot of resources among themselves.could you help me clarify the following:1. can this chip, from a software/hardware point of view, support 2 CAN buses operating at different speeds CAN1=250kbps and CAN2=500kbps for example?2. the delay in sending messages from CAN1 to CAN2 is critical for this device, could someone let me know if problems can arise with this?3. are there any restrictions on the maximum number of TX/RX messages (CAN_IDs) for two buses? As far as I understand, CAN filters are shared to CAN1 and CAN2... Thanks in advance everyone for your help!

Hello,I am dealing with fixed-point arithmetic calculations on STM32G0.To avoid integer overflow risks I have scaled properly all the values involved in calculations, but a mistake can be always possible...On Texas Instruments DSPs, I have the possibility to switch the integer overflow mode, from wrap to saturate, thanks to a couple of intrinsic instructions.Is there such a possibility also on Cortex processors (and in particular on Cortex M0+)?Thank you,Carlo
