Init Failures on VL53L5, L7 and L8 due to long I2C writes The most viewed and commented post on the Imaging page had to do with an Init failure on the multizone part.
These parts have large I2C writes at the beginning, which is downloading the Firmware (on the L5 and L7) and downloading patch updates on the L8.
The solution was:
uint8_t WrMulti(VL53L8CX_Platform *p_platform, uint16_t RegisterAddress, uint8_t *p_values, uint32_t size) {
uint8_t status = HAL_OK; // Initialize status as HAL_OK
uint32_t remaining_size = size; // Calculate remaining size to write
uint16_t current_address = RegisterAddress; // Initialize current address
// Loop until all data is written
while (remaining_size > 0) {
// Calculate the current chunk size to write
uint32_t current_chunk_size = (remaining_size > chunk_size) ? chunk_size : remaining_size;
// Perform write operation for current chunk
status = HAL_I2C_Mem_Write(&hi2c2, addr, current_address, I2C_MEMADD_SIZE_16BIT, p_values, current_chunk_size, 100);
// Check for error
if (status
