I can't find a summary of the colors used in CubeIDE Pinout View. What is the meaning of these different colors?Thanks,

I am having problems with the ANT7-ST25DV04K module. What happens is that when I bring the mobile close to the module to read it, the NFC of the mobile is activated and deactivated all the time and never finishes reading the card. I'm using the ST25 NFC Tag app, but I can't do anything because it doesn't detect the module for the reason I mentioned before.Any solution?

The databrief for this kit doesn't explicitly state that it comes with an antenna, just "SMA female connector".Can someone confirm if it ships with an antenna? If not, any suggestions for one that fits it?

Hello ST,We are working with the ST25RU3993-HPEV board to evaluate the RFID chip.We have performed measurement of the output level on the antenna port and below are the obtained results:For the internal PA:Output level set using ST GUI / Expected output power / Measured output power / Voltage measured0 / 20 dBm / 17.9 dBm / 0.81 V-3 / 17 dBm / 16.064 dBm / 0.78 V-6 / 14 dBm / 14.023 dBm / 0.69 V-9 / 11 dBm / 11.653 dBm / 0.63 V-12 / 8 dBm / 9.18 dBm / 0.56 VFor the external PA:Output level set using ST GUI / Expected output power / Measured output power / Voltage measured0 / 30 dBm / 38.52 dBm / 1.27 V-3 / 17 dBm / 37.85 dBm / 1.27 V-6 / 14 dBm / 35.66 dBm / 1.21 V-9 / 11dBm / 32.86 dBm / 1.14 V-12 / 8dBm / 30.27 dBm / 1.06 VAre the expected output power correct for both internal and external power amplifier?It seems to us that the obtained results from the internal PA configuration are close to the expected one but we are surprised by the obtained measures with the external amplifier.

Hi, I was wondering if you could attach the exposed center pad of the L6234 IC to GND to get better heat dissipation throughout the PCB?The datasheet does not mention anything about the exposed center pad.Thanks!Best regards Niklas Cooke

How do I enter a password on the NFC Tap iOS app when the keyboard covers the action buttons?I'm trying to password protect a ST25TA02KB using NFT Tap for iOS, and having some difficulty. First, it's giving me a, "This is not a type 4A tag" error. If I dismiss that and try to forge ahead and set a password, the iOS keyboard covers up the password entry fields and action buttons (see attached image). So my questions are:Has anyone encountered this and is there a solution?How is a password properly entered in these fields?I have a newborn's knowledge of NFCs, so please be kind. Thanks.

Hello, I am using SPC58EC-Disp board. Core2 is already active and has timer interrupts. I need to set a timer interrupt in Core 0. I am trying use PIT0 and PIT0 configuration is done by Core2 so I think I only need to do PIT0 Channel settings. Two cores are using same vector table but different IVOR tables, I can set PIT0 Channel2 interrupt for Core2 from Core0, Core2 handles that interrupt very well. When I set same interrupt for Core0 from Core0 it goes to IVOR1. Let me explain this way. If I change first red area like 0x2000 | 4 to set interrupt for Core2, interrupt and Core0 work well or if I don't enable interrupt in second red area interrupt doesn't work but Core0 is working well. If I don't do these changes and let it be like in the picture(interrupt is enabled for Core0) it is going to IVOR1 handler always. https://community.st.com/s/feed/0D50X00009XkXkKSAV here Erwan suggests to look LR register. Its 0x00008000. What did I do wrong? And how can I fix it? Thanks in advance.

I'm working on test code for a bare metal STM32G0C1 project. I'm using STM32CubeIDE 1.9.0 and created the project with the included STMCubeMX tool.When digging around in the generated code to understand I2C I found that the function HAL_I2C_MspInit(hi2c) is only weakly defined in stm32g0xx_hal_i2c.c. For other peripherals, such as UARTs, there's a HAL_***_MspInit() where the GPIO are configured. Even supplied sample projects have a HAL_I2C_MspInit(). Instead I find this heart stopping note in stm32g0xx_hal_i2c.c:"(+) User must Implement HAL_I2C_MspInit() function in which he configures     all related peripherals resources (CLOCK, GPIO, DMA, IT and NVIC )."Whoa horse!! What's up with burying such an important little comment deep in the generated source code (that I'm not suppose to muck with and assume is good to go right out of the chute)? I hope you can tell me the error of my ways. Otherwise, I'm going to assign the dreaded "b" word (as in insect) to this ti

Hi, I have compiled the kernel source files and prepared the install artifacts as described in README.HOW_TO.txt, but when I am copying the modules into my STM32MP157C-DK2 board, it gets out of space. Moreover in the board I only have the modules related with this kernel version (5.10.61)The initial configuration was multi_v7_defconfig and I applied all fragments specified (fragment-03-systemd.config, fragment-04-modules.config and fragment-05-signature.config). I do not know if any of these fragments is building a huge amount of modules (that I think I do not really need), or if there is any kind of problem with the partitions (see attached picture), or any other thing.I have seen that there is an step before copying the modules in the board that is used to strip the kernel modules in order to reduce its size, this is:find . -name "*.ko" | xargs $STRIP --strip-debug --remove-section=.comment --remove-section=.note --preserve-dates Nevertheless, when executing the above command, it fai

I desperatly try to configure these applications in order to display 2 buttons on the TFT LCD of my STM32F429I-DISC1 board. Precisely, I'd like to know:If using STMCubeMX is required?How to transfer the TouchGFX layout code into STCubeIDE (I can do an import but then the .ioc file is missing)?I almost succeded by renaming the TouchGFX files before importing them into CubeMX (I replaced the default board name with my project's name). Then I compiled with no errors but once I added two GPIO, the new compilation yields 5 errors (mostly related to TouchGFX HAL).What is wrong with all that??? Is there a workflow of some kind to solve my issue?I appreciate your help. Thank you very much.

Hi Project built with TouchGFX not initializing heap properly:When attempting to allocate a variable to the heap the variable is allocated at 0x00000000 instead of the heap location. This doesn't happen with projects built using cube. Does anyone have any ideas.The screen shots are attached as my browser kept crashing when I tried to embed the images.Project Built with CubeMXProject built with touchGF, but with all TouchGFX code commented out and the MPU initialisation commented out as well:I have asked this question on the support page.The two projects are attached.Best regardsRob

If I set the Counter Period (AutoReload Register) to max 0xFFFF and the TIM capture/compare register to 0xFFFF too, I cannot get a full width output, I still get one tick on output.Is that expected?

For example, sending a 1.5second on-time pulse?  It would also be helpful to be able to set a delay before the pulse starts as well as the 'repetition' of the pulse. The TIMER1 does have the required features but not sure how to scale down the frequency to under 1Hz. Should I chain timers as master/slave to obtain the low frequency?Thanks!

I am not able to get pin PE9 to toggle using timer1 and Channel1 as a PWM Output. I have tried different configurations for the timer with no success. The timer does run as expected, and all parameters and interrupts work. The only issue is pin PE9 does not toggle or enable at any time while the timer runs.UPDATE: I connected the pin to one of the dev board's leds and it does turn on as expected. For some reason, when I use the following to inspect the pin status, it always shows as '0' or off. Does anyone know why the led turns on but the GPIOE would show '0' when I stop the debugger to inspect the register?Here is my config for TIM1: TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; TIM_OC_InitTypeDef sConfigOC = {0}; TIM_BreakDeadTimeConfigTypeDef sBreakDeadTimeConfig = {0}; /* USER CODE BEGIN TIM1_Init 1 */ /* USER CODE END TIM1_Init 1 */ htim1.Instance = TIM1; htim1.Init.Prescaler =
