WeAct BluePill + : SPI1 does not work (works with older generic BluePills !) Hi all I made a little program under arduino IDE (but I write directly into the registers), in order to test the command of WS2812b chips via the SPI1 MOSI pin : It worked perfectly with older BluPill boards I have got.Tried the same thing with BluePill + from WeAct official store , it does not work. Even the SPI1->CR1 register is not set properly : it must be 0b1100111 , but it is actually 0b100011 : which is wrong , the Master Mode and SPI enable bits can not be set ...Any idea , please ? thanks !/* spi_dma_ws.h */
#define ws_chips 8 // number of RGB chips
void spi_dma_transmit();
extern SPI_HandleTypeDef hspi1;
extern uint16_t adc_pa5;
// some colours
const uint8_t ws_black[3] = { 0, 0, 0 };
const uint8_t ws_green[3] = { 25, 0, 0 };
uint8_t ws_green_adc[3] = { 0, 0, 0 };
const uint8_t ws_red[3] = { 0, 25, 0 };
const uint8_t ws_blue[3] = { 0, 0, 25 };
const uint8_t ws_white[3] = { 25, 25, 25 };
const uint8_t ws_purple[3] = { 0, 25, 25 };
