I have given the code below, which I know ignores the delay specified in the CDL. Is there a different way to write the code so that the delay and AGR of the CDL get applied? uint16_t smbus_read_word(uint8_t address, uint8_t command) { cyg_i2c_device device = { \ .i2c_bus = &cyg_i2c0_bus, \ .i2c_address = address, \ .i2c_flags = 0, \ .i2c_delay = i2c_bus_time \ }; cyg_uint8 buffer[1]; cyg_uint8 input[2]; buffer[0] = command; cyg_i2c_transaction_begin(&device); if(!cyg_i2c_transaction_tx(&device, true, &buffer[0], 1, false)) { diag_printf("Read Word: fail TX.\n"); } else if(!cyg_i2c_transaction_rx(&device, true, &input[0], 2, true, true)) { diag_printf("Read Word: fail RX.\n"); } cyg_i2c_transaction_end(&device); return input[1] << 8 | input[0]; } -- You are receiving this mail because: You are on the CC list for the bug.
