From f3d370a7778dc8e374efc3b76e26f8ecefc27e84 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Sun, 17 Jan 2010 04:39:33 +0000 Subject: Clean up and add more comments to the AVRISP-MKII project. Make sure the SPI_MULTI command handler supports multiple packet responses. Use slightly smaller/faster repeated indirect-load commands when retrieving the PDI target's memory CRCs. --- Projects/AVRISP-MKII/Lib/V2Protocol.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'Projects/AVRISP-MKII/Lib/V2Protocol.c') diff --git a/Projects/AVRISP-MKII/Lib/V2Protocol.c b/Projects/AVRISP-MKII/Lib/V2Protocol.c index 093c07862e..976f24b9e3 100644 --- a/Projects/AVRISP-MKII/Lib/V2Protocol.c +++ b/Projects/AVRISP-MKII/Lib/V2Protocol.c @@ -58,6 +58,7 @@ void V2Protocol_ProcessCommand(void) { uint8_t V2Command = Endpoint_Read_Byte(); + /* Set total command processing timeout value, enable timeout management interrupt */ TimeoutMSRemaining = COMMAND_TIMEOUT_MS; TIMSK0 |= (1 << OCIE0A); @@ -121,6 +122,7 @@ void V2Protocol_ProcessCommand(void) break; } + /* Disable timeout management interrupt once processing has completed */ TIMSK0 &= ~(1 << OCIE0A); Endpoint_WaitUntilReady(); @@ -162,8 +164,8 @@ static void V2Protocol_SignOn(void) Endpoint_ClearIN(); } -/** Handler for the CMD_RESET_PROTECTION command, currently implemented as a dummy ACK function - * as no ISP short-circuit protection is currently implemented. +/** Handler for the CMD_RESET_PROTECTION command, implemented as a dummy ACK function as + * no target short-circuit protection is currently implemented. */ static void V2Protocol_ResetProtection(void) { -- cgit v1.2.3
