Changes
• File structur e was organized.
Known issues (Carried Forward)
LPCOpen v3.01 release (Released: 04/06/2017)
Project and Example updates
Features Added
• V2 LPCOpen code was converted to V3 LPCOpen. This simplifies code structure and decrease path
lengths, LPCOpen has been reorganized to a flatter structure. These changes have been made in an
effort to improve usability and maintainability of LPCOpen software
Changes
• I2c_rom: renamed the address to reflect the 8-bit value was ADDR7BIT now ADDR8BIT
• I2cm_8xx.h: Added check for error condition of not completing a transaction
• gpio_8xx.h: Fixed the mask for IO bits (was 8-bit char, and is now 32 bits)
• Updated ring_buffer.c, and ring_buffer.h files
• Board setup file updated to allow selection of XTAL
• I2C master example: "status" in "I2CM_XFER_T" was made "volatile"
In function "Chip_I2CM_XferHandler", member "status" in "I2CM_XFER_T" set to "STATUS_OK" only
after "I2C_STAT_MSTCODE_IDLE" flag is set). Also, "I2C_INTENSET_MSTPENDING" IRQ was
disabled (can use “Chip_I2C_ClearInt (pI2C, I2C_INTENSET_MSTPENDING);”) when
I2C_STAT_MSTCODE_IDLE is detected (master job is done) to prevent unwanted IRQ firing.
• I2C slave: "Chip_I2CS_SlaveContinue(pI2C);" should be called in slave ISR even if
"I2C_INTENSET_SLVDESEL" flag is set
• Updated GPIO API file
• uart_8xx.c:
o Fixed the print string to calculate length correctly
o In function “Chip_UART_ReadBlocking”, the judgement "while (readBytes < numBytes)" is
wrong. Was changed to "while (numBytes > 0)
o Should be int Chip_UART_ReadBlocking(LPC_USART_T *pUART, void *data, int numBytes)
• mbed MAX board has CMSIS_DAP debugger software as default. All projects need to be configured to
use CMSIS-DAP as default.
• In IAR, all examples have wrong path. It checks for examples_81x instead of example_82x.
• periph_dma_mem and periph_dma_uart: Fixed hard fault during execution.
