Hi Victor Three points here need you to check: 1. The slave address is right? 2. Can you try to decrease the frequency of your CLK? 3. If nothing help, can you try use two msp430 launchpad to test the code fisrt?\ Best regards Gary

Forum Post: RE: MSP-EXP430FR5969: Modify EXP430FR5969 to 3 V
Hi Rudnik, The onboard eZ-FET of MSP-EXP430FR5969 only support a fixed voltage power supply. You need change to the MSP-FET programmer and debugger , connect the pins of MSP-FET to the eZ-FET jumpers of MSP-EXP430FR5969, which supports target VCC to be selectable in a range between 1.8 V and 3.6 V in steps of 0.1 V. You could see the details on section 3.4&5 of this document: For changing the target voltage supply, go to CCS project and right click your project name->Properties->Debug->MSP43x Options->Target Voltage

Hi Adrian The libraries and GUI is developed for the water meter so far of the MSP430FR6047 with the ultrasonic. You can just use the USS module has a dedicated clock module, HSPLL, which generates a very-lowjitter clock (68 MHz to 80 MHz) from the USSXT oscillator. The SAPH controls the signal flow including excitation pulse generation through a low-impedance driver (4 Ω, typical), internal bias voltages for Tx and Rx sides, and the input multiplexer. The SDHS is a high-speed analog-to-digital converter to sample the input signals and transfer the output data to the target memory location. The Low Energy Accelerator (LEA), if available, processes the data transferred by the SDHS. Best regards Gary

Hi Bryan, I could find a blog about this topic, which could give you some idea. e2e.ti.com/.../helpful-tips-executing-code-from-ram But could you share me your project so that I could run it on my side check if anywhere has problem? BTW, as I will have national holiday in China for the coming whole week. I would like to look deep in your case after 10/8. Please feel free to reply for any update of your issue.

Forum Post: RE: MSP430FR5969: Unable to Reset Rx Shift Register for SPI Slave
Hi Gadiel I don't know whether your application meet the two conditions: 1. The eUSCI_A or eUSCI_B module is configured as a SPI slave with clock phase mode UCCKPH = 1 AND 2. The SPI clock pin is not at the appropriate idle level (low for UCCKPL = 0, high for UCCKPL = 1) when the UCSWRST bit in the UCxxCTLW0 register is cleared. If so you can refer to the bug USCI47( www.ti.com/.../slaz473y.pdf) Best regards Gary

Forum Post: RE: CCS/MSP430FR5949: JTAG issue, Error connecting to the target: The Debug Interface to the device has been secured
Hi Zrno, I think I understand why it does not work. The BSL doesn't get initiated properly. For that there must be a standard reset sequence as per SLAU550p, page 7. This involves both the RESET line (pin 11 of the 14 pin JTAG header) and the TEST line(pin 8 of the JTAG header). RESET (JTAG pin 11) must be connected to the RST/NMI of the target but with a SBW setup pin 11 is not connected and the target RST/NMI pin is connected to to JTAG pin 1 (TDO/TDI) My conclusion is that you need to have the full blown JTAG connections implemented and not SBW to make BSL work. Can you confirm that? If my conclusion is correct, I can jumper the RESET pin of the JTAG connector to the RST/NMI pin of my target, asuming the TDO/TDI pin is not used in BSL operations.

Hi Zrno, I connected pins 1 and 11 of my JTAG connector and it looks the BSL is responding but still an error on the MASS-ERASE command, see below. Any idea what this can be?

Forum Post: RE: RTOS/MSP430FR6047: CHIRP receiver
Hi Gary, thanks for your reply. As I mentioned before, I have the trasmitter ready in terms of HW and now I need to proceed with the receiver. I would like to get the signal from the ADC and perform decimation and filtering. Later, I need to match the received signal with my transmission signal. What I liked the most about the mentioned board was the idea of avoiding BGA in an FPGA development by the use of LEA. I do not know if I will be able to perform the reception in real time yet. Might you tell me more about what you proposed? Thanks

Forum Post: CCS/MSP430FR2355: Problem using IE1 register for MSP430 Low Power MCU.
Part Number: MSP430FR2355 Tool/software: Code Composer Studio Hello. I was coding for MSP430 ( msp430fr2355 ) in CCS(Version: 8.1.0.00011 ) to write a program which uses watchdog timer as an interval timer to generate interrupts at every 1 second using ACLK. the error I'm getting is identifier "IE1" is undefined. which corresponds to the interrupt flag register for Watchdog timer. Given above is the basic code I've written. #include int main(void) { PM5CTL0&=~LOCKLPM5; WDTCTL = WDT_ADLY_1000; // stop watchdog timer P1DIR=BIT0; IE1| = WDTIE; _enable_interrupts(); while(1); return 0; } #pragma vector=WDT_VECTOR __interrupt void wdtled(void) { P1OUT=BIT0; __delay_cycles(100000); P1OUT=0x00; __delay_cycles(100000); } I have gone through many example codes posted in the e2e community and most of them used this IE1 register but I' unable to use this. If anyone knows the solution , please help me as soon as possible. Thanks in advance!

Thanks for your answered. In debug mode I press resume to run my code . I found my code stop after run the loop few times. The transmit interrupt flag was pulled up.,and all the RX buffer receive the 0x00FF. I can't received the new data from the sensor . Is that any problem with my code.

Forum Post: RE: MSP430F149: Resetting the micro while reset vector is 0xFFFF
As Bruce said, it is likely that the boot code will detect this and force the CPU to go to sleep. But if it doesn't, the bytes FF FF will be interpreted as ADD.B @R15+,X(R15), where X are the contents of the following word; after wrapping around, this is the IE1 register at address 0000. (Later families are documented to reset when trying to execute inside the I/O range.)

The ninth bit is 1, which is a NACK. In other words, the slave did not answer. The I²C slave address has 7 bits, so 0xD6 cannot be a valid address. I guess the actuall address is 0x6B?

You have to assignments for the same interrupt vector. You have to merge both functions.

It appears that on FR2xx devices, the IE1 register is not called IE1 but SFRIE1.
