From 8f3bee7d8661c92ce69fdf7cc131fbee1acaa4ae Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Sun, 24 Oct 2010 12:25:34 +0000 Subject: Better algorithm to extract and convert the internal device serial number into a string descriptor (if present). Fix incorrect warning text when an unsuitable F_CLOCK value is given. --- LUFA/Drivers/USB/HighLevel/DeviceStandardReq.c | 10 +++++----- LUFA/Drivers/USB/LowLevel/USBController.h | 2 +- 2 files changed, 6 insertions(+), 6 deletions(-) (limited to 'LUFA/Drivers') diff --git a/LUFA/Drivers/USB/HighLevel/DeviceStandardReq.c b/LUFA/Drivers/USB/HighLevel/DeviceStandardReq.c index 960e24367..8b8f0c0eb 100644 --- a/LUFA/Drivers/USB/HighLevel/DeviceStandardReq.c +++ b/LUFA/Drivers/USB/HighLevel/DeviceStandardReq.c @@ -211,8 +211,8 @@ static void USB_Device_GetConfiguration(void) #if !defined(NO_INTERNAL_SERIAL) && (USE_INTERNAL_SERIAL != NO_DESCRIPTOR) static char USB_Device_NibbleToASCII(uint8_t Nibble) { - Nibble = ((Nibble & 0x0F) + '0'); - return (Nibble > '9') ?
