using multiple device with SPI connection problem

[AzwarPrihastomo]

I just found bug on this code
if we using multiple BMP388 with SPI
i found the reading on first initialized device is error

after i check the pointer for SPI is on global variable
Adafruit_SPIDevice *spi_dev = NULL; ///< Global SPI interface pointer

so i move this variable on local class variable

and change this 2 function
//
/*!
@brief Reads 8 bit values over SPI
*/
//
static int8_t spi_read(uint8_t reg_addr, uint8_t *reg_data, uint32_t len,
void *intf_ptr) {
((Adafruit_SPIDevice)intf_ptr)*->write_then_read(&reg_addr, 1, reg_data, len, 0xFF);
return 0;
}

//
/*!
@brief Writes 8 bit values over SPI
*/
//
static int8_t spi_write(uint8_t reg_addr, const uint8_t *reg_data, uint32_t len,
void *intf_ptr) {
((Adafruit_SPIDevice)intf_ptr)*->write((uint8_t *)reg_data, len, &reg_addr, 1);

return 0;
}

it solve the issue

Thanks

I am stuck with this too, Would you mind to provide a bit more detail?

you can try #19

Closing due to lack of response. Linked release above should resolve this.
