From 0220782aa86d84a9f11b37f32bb0be5e3cd58ca6 Mon Sep 17 00:00:00 2001 From: John Van Ostrand Date: Wed, 6 Sep 2017 16:02:04 -0400 Subject: [PATCH] Change communication parameter to work better with FTDI The parameters used with the FTDI USB serial port drivers didn't work well with directly with libftdi1. The new baud rate results in the same effective baud rates for both. The rbstream block size was reduced to help with the unreliability of the libftdi communications. --- src/cochran_commander.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/src/cochran_commander.c b/src/cochran_commander.c index f079c09..525db90 100644 --- a/src/cochran_commander.c +++ b/src/cochran_commander.c @@ -199,8 +199,8 @@ static const cochran_device_layout_t cochran_emc14_device_layout = { COCHRAN_MODEL_EMC_14, // model 32, // address_bits ENDIAN_LE, // endian - 806400, // baudrate - 65536, // rbstream_size + 850000, // baudrate + 32768, // rbstream_size 0x0D2, // cf_dive_count 0x13E, // cf_last_log 0x142, // cf_last_interdive @@ -224,8 +224,8 @@ static const cochran_device_layout_t cochran_emc16_device_layout = { COCHRAN_MODEL_EMC_16, // model 32, // address_bits ENDIAN_LE, // endian - 806400, // baudrate - 65536, // rbstream_size + 850000, // baudrate + 32768, // rbstream_size 0x0D2, // cf_dive_count 0x13E, // cf_last_log 0x142, // cf_last_interdive @@ -249,8 +249,8 @@ static const cochran_device_layout_t cochran_emc20_device_layout = { COCHRAN_MODEL_EMC_20, // model 32, // address_bits ENDIAN_LE, // endian - 806400, // baudrate - 65536, // rbstream_size + 850000, // baudrate + 32768, // rbstream_size 0x0D2, // cf_dive_count 0x13E, // cf_last_log 0x142, // cf_last_interdive @@ -372,7 +372,7 @@ cochran_commander_packet (cochran_commander_device_t *device, dc_event_progress_ // Give the DC time to process the command. dc_serial_sleep(device->port, 45); - // Rates are odd, like 806400 for the EMC, 115200 for commander + // Rates are odd, like 850400 for the EMC, 115200 for commander status = dc_serial_configure(device->port, device->layout->baudrate, 8, DC_PARITY_NONE, DC_STOPBITS_TWO, DC_FLOWCONTROL_NONE); if (status != DC_STATUS_SUCCESS) { ERROR (abstract->context, "Failed to set the high baud rate."); @@ -523,7 +523,7 @@ cochran_commander_read (cochran_commander_device_t *device, dc_event_progress_t return DC_STATUS_UNSUPPORTED; } - dc_serial_sleep(device->port, 800); + dc_serial_sleep(device->port, 550); // set back to 9600 baud rc = cochran_commander_serial_setup(device);
