Remapping and multiplexing

Now let's talk about the port remapping of the STM32 microcontroller, as it is an example of itself. Here is an example of the remapping of the USART1:Because I want a TFT_LCD screen of the main control board, taking into account the FSMC I chose the STM32F103VCT6 model of the CPU, accidentally connected to the serial port USART1. Because in the tuning process only found wrong, there is no way, can only be resolved by port remapping. But it didn't work. Port remapping , only the name, not the bo

test points, the relevant design requirements are as follows:(1) test points evenly distributed across the entire PCB, it is generally required that each network must have at least one Test probe to contact the testing point.(2) Priority of the test point selection: preferably a round pad, followed by the device pinout, the last hole is the most test point. SMD devices preferably using a circular pad to do test points, OSP processing process PCB shou

Use the clock resources provided by the FPGA as much as possible, using DCM as Deskew.Offset constraint not satisfiedThe first thing to do is to ensure that offset is written correctly.Then ensure that the input/output data into the FPGA in the register with a beat, the middle do not add the combination of logic.

modes rdat and RCMD: Used to prevent DAT and CMD from being flushed when no card is inserted or when all cards are in the high-impedance status 5. SPI ModeThe SPI mode contains an optional communication protocol provided by a flash-based mmccard, it is mainly defined for situations where the system does not have a dedicated MMC host controller and does not have high communication speed requirements. SPI defines only one physical connection Standard for MMC communication, with only one subset of

STM32 UART Single-line half-duplex mode (cube version)

STM32 UART Single-line half-duplex mode (cube version) 1. IntroductionIn some cases, a three-wire serial communication is required (only one of the signal lines), which requires a single-line half-duplex mode for communication. In this case, in the process of data protocol transmission, the signal end needs to switch back and forth in the input and output mode. Alternatively, the transmit and interface of the control port can be short-connected. In this case, STM32 provides the Half-duplex funct

bit reserved, low 16 can be read at any time, 1 means the corresponding configuration bit is activated latch, 0 means can be activated, activation is a fixed write shunThe order. Latches can not be used indiscriminately, if a function register of a port is locked, then the function of the port can not be changed before the next system reset, which is advantageous in some cases, especially if the program is heavyWhen defining the functionality of certain GPIO ports, it is necessary to ensure tha

STM32 Cube Usage Precautions

1. In the pinout option, all the system used pins are configured, including two osc,jtag/swd, BOOT0/1, so that all unused pins can be set to analog, otherwise it will not download the program.2. For the JTAG has been configured for other functions, but unable to write the program, the boot0 changed to 1 and then press reset and then the emulator is good, because boot0 changed to 1, does not start from flash, JTAG pin will not be initialized, When usin

[IIS] IIS Literacy (i)

Iis-iis Concept Related1. IIS (Inter-ic Sound bus), also known as I2S, is a serial digital audio bus protocol proposed by Philip. Currently, many audio chips and MCUs provide support for IIS. The IIS bus processes only sound data. Other signals, such as control signals, must be transmitted separately. To keep the chip's pinout as small as possible, IIS uses only three serial buses. These three lines are: data lines that provide time-sharing, field sel
